Cardizem Intravenous and Inderal

Determining the interaction of Cardizem Intravenous and Inderal and the possibility of their joint administration.

Check result:
Cardizem Intravenous <> Inderal
Relevance: 08.11.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Using propranolol and dilTIAZem together may lead to increased side effects. This can cause fatigue, headache, fainting, swelling of the extremities, weight gain, shortness of breath, chest pain, increased or decreased heartbeat, or irregular heartbeat. If you take both medications together, tell your doctor if you have any of these symptoms. You may need a dose adjustment or need your blood pressure checked more often to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

MONITOR CLOSELY: Additive reductions in heart rate, cardiac conduction, and cardiac contractility may occur when calcium channel blockers, especially verapamil and diltiazem, are used concomitantly with beta blockers. While this combination may be useful and effective in some situations, potentially serious cardiovascular adverse effects such as congestive heart failure, severe hypotension, and/or exacerbation of angina may occur. Ventricular asystole, sinus arrest, and heart block have also been reported. The risk is increased with high dosages, IV administration, left ventricular dysfunction, or AV conduction abnormalities. Beta blocker ophthalmic solutions may also interact, as they are systemically absorbed and can produce clinically significant systemic effects even at low or undetectable plasma levels. Bradycardia (36 bpm) with wandering atrial pacemaker occurred in a patient taking oral verapamil and timolol ophthalmic drops. The proposed mechanisms include additive slowing in AV conduction, reduced cardiac contractility secondary to beta-blockade, and decreased peripheral vascular resistance secondary to calcium channel blockade. In addition, verapamil and diltiazem may decrease the clearance of some beta blockers and use of diltiazem with beta blockers has been associated with an increased risk of depression.

MANAGEMENT: Close clinical monitoring of patient hemodynamic response and tolerance is recommended if these agents are used together, and the dosage of one or both agents adjusted as necessary. Patients should be advised to promptly report any symptoms including fatigue, headache, fainting, swelling of the extremities, weight gain, shortness of breath, chest pain, increased or decreased heartbeat, or irregular heartbeat.
